Dynapower
Product: MPS-i-125 EHV Energy Storage
System
Description: The MPS-i-125 EHV is a
fully integrated behind-the-meter energy storage system. The MPS-i-125 EHV couples Dynapower's efficient UL 1741 SA MPS-
125 EHV inverter with Li-ion batteries in a temperature controlled battery NEMA-rated enclosure. The highly compact integrated system is easily deployed on a concrete pad, crushed stone, or on the ground with a forklift and minimal labor, reducing system installation costs for integrators and system owners.
The system features Dynapower’s Dynamic Transfer which, in the event of grid disturbance, seamlessly switches a facility from grid-tied
to battery backup power. Multiple MPS-i-125 EHV systems can be paralleled together to meet the sizing needs of any behind-the-meter installation.
Chemistry: Lithium-ion
Voltage: 480 - 600 VAC 3 Phase
Peak power: 125kW @ 480V, 150kW @ 600V
Operating temperature range: -31°F to 122°F (-35°C to 50°C)
Certifications: Inverter: IEEE 1547, UL 1741 SA Listing
